PHP中的count_chars，其中字符数大于16

Question

So for some reason when I use count_chars(11111111111111111111,3) I get back something to the effect of .1111111111111119

Is there a different way to count the occurences of each character in a string?

Here's some example code

            $value = 11111111111111111111; 
            $value = strval($value);
            $count = count_chars($value,3);
            print_r($count);

If I print out the result I get +.012E

If you want to count characters in string, give a string...

count_chars('11111111111111111111',3)

ps: and if you really want to count characters use mode 1

 $res = count_chars('1111111111111111111122333', 1);

 foreach ($res as $char => $number) {
  echo chr($char). ' ' . $number .'<br />';
 }
